1. Since the bearing is designed to have the appropriate internal axial clearance, there is no need for pre-load addition adjustment (dimensional adjustment for spacers), which is necessary for singly row bearing assembly.

2. Greasing.

3. An appropriate amount of high-grade grease (excellent for hear 130degree and wear resistant) is pre packed in the bearings.

4.  Sealed type bearings are mud-proof, dust-proof, and leak-proof (grease) all without the use of shaft seals.

5.  High refining bearing steel can be used or the bearing, thereby extending its service life.
